This invention relates to closures for nonrefillable containers, and its object is to provide an improved closure for bottle or other containers, that will allow the free passage of the contents being also provided at its lower face with two opposed vertical pins I 4I4 in alignment with said conduits ll 6.

The closure, which may the opposed vertical holes I9i9 of the disc be made of glass or the like, will preferably be N3 of stem !'I. made of a plastic material, and it includes a As it will be obvious, the run of the stem 11 hollow cylindrical body 3 in the shape of an inis lim t d by the P s i4|4 inferiorly Carried verted cup having its upper end provided with by the partially hollow cylindrical body In (Fig. a central opening 5 and its lower end provided 5) and the top plane face of the solid cylindrical with an outer annular flange 4.

The operation of this closure is as follows: When it is desired to pour the contents of the bottle therefrom, the bottle is tilted, whereupon the stem 1'! will slide onward within the central square perforation 15 until the top face of the disc [8 inferiorly carried by it will rest on the pins i ll4 disposed on the lower face of partial-; 1y hollow cylindrical body HI, and the upper hori zontal perforation 2| of the stem I! will be in communication with the space between the disc I of body 3 and the top face of partially hollow cylindrical body l and the lower perforation 20, of the stem I! will register with angular conduits i6l6 of partially hollow cylindrical body [0. Outer air entering in the opening of the top portion of hollow body 3 will pass through hole 8 of disc 1, upper perforation 2|, central conduit 22 and lower perforation of stem ll, angular conduit i6, hole :9 of disc [8 of stem ll, and vertical hole 2'! of the solid cylindrical body 23. Obviously, liquid from the bottle will be permitted to flow freely through opposed perforations and conduits of the closure parts, to find its way out, through upper opening 5 of hollow body 3.

Many changes may be made in the shape and in the nature of the material of which the closure is formed, provided that such changes fall: within the scope of the appended claims.

What I claim is: 1

1. A closure for non-refillable containers, comprising a hollow cylindrical body of inverted cup shape provided with a top central opening and having arranged therein and formed therewith a perforated disc, said cylindrical hollow body carrying at its lower end an outer annular flange, a partially hollow cylindrical body arranged within said hollow body and provided at its upper solid middle portion with a vertical central square perforation and at the lower face of its upper solid portion with two opposed pins and two opposed angular conduits and in communication with said central square perforation, said partially hollow cylindrical body being also provided at the end of its lower hollow portion with an outer annular flange on which normally rests the outer flange of said hollow cylindrical body, a

solid cylindrical body inserted in the lower hollow portion of said partially hollow body and having two opposed vertical perforations and two opposed pins at its top face, said solid cylindrical them adapted to register with the angular conduits of said partially hollow body, in the inverted position of the container, in which the other transverse perforation of said stem is above the partially hollow cylindrical body said square stem having its lower end fixedly secured to the middle portion of a disc provided with opposed vertical holes, and means for securing the closure exteriorly on the container neck.

2. A closure for non-refillable containers, comprising a hollow cylindrical body of inverted cup shape provided with a top central hole and having. its lower end provided with an outer annular flange, said hollow cylindrical body having arranged therein and formed therewith a disc provided with two vertical opposed holes and having inner threads arranged at a short'distance beneath said disc, a partially hollow cylindrical body having an upper solid portion provided with a vertical central square perforation and provided at its lower face with two angular conduits and in communication with said central square hole, said partially hollow cylindrical body being provided at its lower hollow end with an outer annular flange having two opposed peripherial notches and being normally in contact with the outer annular flange of said hollow "cylindrical body, and the solid portion of said partially hollow cylindrical body being provided with outer thread to be threaded on the inner threads of said hollow cylindrical body; a solid cylindrical body the; lower portion of which normally re mains lodged within the container neck, said solid cylindrical body carrying at its middle peripherial portion an outer annular flange adapted to serve as a seat for the closure on the container neck and; having at its upper edge two opposed pins adapted to be insertedin the peripherial notches of the partially hollow cylindrical body, and said solid portion having at its top plane face two opposed pins and two equidistant vertical holes serving as air inlet. and liquid; outlet, a solid square stem partially inserted and freely slidable withinthe central square hole of said partially hollow cylindrical body and having two transverse perforations; one of said transverse perforations being adapted to register with said angular conduits in the inverted position of the container while the other transverse perforation is above the partiall hollow cylindrical body in communication. by a central vertical conduit, said. solid square stem having its lower end fixedly secured to. the middle. plane portion of a disc, provided with two opposed vertical holes, and meansv for securing the closure exteriorly to container neck. and. consisting of a melted layer of plastic material. 7
